IM PROVED EVAPO RATO R.

Specification forming part of Letters Patent No. 57,327, dated August 21, 1866.

To all whom it may concern:

Be it known that I, WILLIAM H. ISAAGS, of Terre Haute, in the county of Vigo and State of Indiana, have made a new and useful Improvement in Evaporators; and I do hereby declare the following to be a full, clear, and exact description of the nature, construction, and operation of the same, suflicient to enable one skilled in the art to which it appertains to construct and use the same, reference being had to the accompanying drawings, which shows my invention in a perspective view.

The improvement consists in the provision of holders against which to strike the inverted skimmer to remove the warm scum, and on which to rest it to drain or when temporarilydisused; also, in the arrangement for retaining the skimmer in the required position in the pan. In these respects my invention is an improvement upon the patent of Jacob E. Moeller, No. 51,256, dated November 28, 1865.

In the drawings, A is the pan. One side is inclined and may project from over the fireplace, so as to make the scum collect at this the cooler side.

B is the skimmer, which is hinged at G and G by straps, which clasp the pivotal rod which forms the axis on which the skimmer rot-ates. The skimmer is a shallow trayof reticulated or perforated metal, and is maintained in the required position in the pan by means of the handles D D, which catch in such of the notches E E on the upper edge of the pan as may be necessary.

The adjustment in question is convenient in varying qualities or depths of liquid, and a body of scum being collected in the skimmer, it being elevated and drained, and then being folded over and thereby inverted, it may be struck sharply against the holders F F, which will remove the warm scum from the surface and perforations and thus cleanse it ready for another turn of duty.

When the skimming-trap is temporarily out of use it rests in an inverted position on the holders without straining the hinges, and by nnfastening the strap 0 it may be withdrawn and laid away in a place of safety, while the pan at other seasons of the year is used for boiling feed for stock, making apple-butter, 850.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The arrangement with the fan of the hold ers F F, substantially as and for the purpose described. 7

2. The handles D D, in combination with the skimmer and the notches or their equivalent in the pan, substantially as and for the purpose described.

The above specification of my improvement in evaporators signed this 1st day of June, 1866.

WILLIAM H. ISAACS.
